PIN-SETTING TOOL.

Specification of Letters Patent.

Patented Nov. 7, 1911.

Application filed October 8, 1910. Serial No. 585,938.

To all whom it may concern:

Be it known that I, JOSEPH B. DERFINAK, a citizen of the United States,residing at Mystic, in the county of New London and State ofConnecticut, have invented certain new and useful Improvements inPin-Setting Tools, of which the following is a specification.

The object of this invention is to provide a simple form of hand tool bymeans of which pins may be rapidly and conveniently driven into wood, orthe like material; the said tool being particularly useful for settingpins in so-called sand-rolls of the class used for taking up a web ofpile fabric, like velvet, in velvet-weaving looms.

My invention is illustrated in the annexed drawings, Figure 1 being anedge view of a tool embodying my present improvement, showing also atransverse sectional view of a roll in which several pins have beeninserted. Fig. 2 is a face, or fiat side, view of said tool and shows alongitudinal, central, sectional, view of a portion of said roll, andFig. 3 is a longitudinal, central, sectional, view of the said tool.

Referring to these drawings, the numeral 10 indicates the body portionof said tool, the same being drawn down at one end portion to provide atang or shank 11 upon which is secured a handle 12. The body 10 isdrilled longitudinally to provide two parallel holes in which areslidably mounted rods 13 to whose outer end is fixedly secured a plate14, and the said parallel holes are counterbored to receive springs 15that surround the rods 13 and abut the inner face of the plate 1 1 insuch manner that the springs seek constantly to force the plate outward,that is to say, away from the body 10, such outward movement beinglimited however, by a stop pin 13* inserted in one or both of the rods13. The plate 1 1 is provided with one or more holes 16 in which pins (4may be loosely entered, the body 10 being provided with depressionsadapted to receive the pin points and thus hold said pins in alinenientwith the holes 16. It will of course be understood that, normally, theplate 14c is forced outwardly by springs 15, as seen in Fig. 1 of thedrawings.

IV hen the pin is inserted in the hole of plate 14; and the pin endrests in the described depression, the plate serves to steady the pinand to guide it straight as it is being forced into the wood; the platemeanwhile resting against the wood. As the pin is forced home thesprings 15 yield and the body 10 pushes the pin or pins through theplate 14:, as will be understood by reference to Figs. 2 and 3.

By preference I insert in the body 10 short sections 17 of wire whoseouter ends are prick-punched eccentric to the circumference of saidwire, so that the depressions thus provided for the pin points may beadjusted to line up with the hole in plate 14 by partially rotating thesaid wire 17. I also provide set-screws 18 by means of which the wiresmay be clamped in position after they have been thus adjusted.

By the use of my improved tool I am able to set the pins very rapidlywithout the liability of bending the pins and with absolute accuracy asto the length of that portion of the pin that remains projecting fromthe wood.

Having thus described my invention I claim 1. In a pin setting tool, abody portion provided with a tang, a handle upon said tang, said bodybeing provided with longitudinally disposed parallel holes, rodsslidably mounted in said holes, a plate fixedly secured to the outerends of said rods, springs acting to force said plate outwardly awayfrom the body, means for limiting such outward movement, said platebeing provided with pin-receiving openings.

2. In a pin setting tool, a body portion provided with a tang, a handleupon said tang, said body being provided with depressions to receive pinpoints and with longitudinally disposed parallel holes, rods slidablymounted in said holes, a plate fixedly secured to the outer ends of saidrods, springs acting to force said plate outwardly away from the body,means for limiting such outward movement, said plate being provided withpinreceiving openings, and means in said body for alining the saiddepressions with the openings in the plate.
